Vic killer jailed for teen boy's murder

The family of a teenage boy murdered by a man wearing brass knuckledusters filled a courtroom with applause - and verbal abuse - as the killer was jailed in Melbourne.

Thomas Kelson, 29, has been sentenced to 24 years' imprisonment for murdering 17-year-old Cayleb Hough, whose body was found in the Lerderderg State Park near Macedon in March 2016, about three months after he died.

As he was lead out of the docks at the Supreme Court of Victoria on Friday, Cayleb's family screamed "you crumb" and "you filthy scum" at the killer, who will be eligible for parole in 19 years.

In sentencing, Justice Andrew Tinney condemned the "violent and protracted assault" and "absolute tragedy" of Cayleb's death at the hands of someone who'd been a friend.

He said the pair had been at a party and both consumed drugs and alcohol, becoming "on edge".

The next day, on December 20, 2015, the pair attended a friend's address at Collingwood, smoking ice and "speaking in riddles" as they become more drug-affected.

During their time at Collingwood, Kelson became concerned about the disappearance of his father, incorrectly believing Cayleb had something to do with it.
